Core Views - The chemical market is generally under pressure from demand, with different products facing various supply - demand situations. Positive and negative factors coexist, and investors need to pay attention to specific product trends and relevant influencing factors [2][3][5][6][7][8] 3. Summaries by Directory Olefins - Polyolefins - Propylene futures had narrow intraday fluctuations. The demand is weak, but the maintenance of Binzhou PDH device may support price stabilization [2] - Plastic and polypropylene futures declined. The supply of polyethylene increased due to reduced maintenance and new production, while demand weakened. Polypropylene faced supply pressure from new capacity and reduced maintenance, and demand was limited by low profit [2] Pure Benzene - Styrene - Pure benzene futures oscillated around 5,500 yuan/ton. The port inventory increased, and there are medium - term negatives. The strategy is mainly month - spread reverse arbitrage [3] - Styrene futures were weak. The cost support was insufficient, and the high inventory pressure continued [3] Polyester - PX and PTA prices fluctuated. Supply increased, and there was a risk of inventory accumulation. The strategy is reverse arbitrage [5] - Ethylene glycol production decreased slightly, but inventory increased. The supply pressure is high, and the strategy is reverse arbitrage [5] - Short fiber had a good spot pattern but may face inventory accumulation in mid - to late November. Bottle chip demand weakened, and the cost was the main driver [5] Coal Chemical Industry - Methanol prices fell sharply. High inventory and weak demand persisted, waiting for supply reduction and demand improvement [6] - Urea prices oscillated narrowly. Downstream demand increased, and inventory decreased, but the market may continue to oscillate at a low level [6] Chlor - Alkali - PVC was at a low level due to weak cost support, high supply, and weak demand [7] - Caustic soda prices were slightly stronger, but high inventory and weak demand may keep prices low. Attention should be paid to liquid chlorine prices [7] Soda Ash - Glass - Soda ash prices declined due to increased supply and reduced demand. Consider the strategy of long glass and short soda ash [8] - Glass prices rose. Inventory is expected to decrease, but cost increase and insufficient orders may limit the rise [8]

Group 1: Report Industry Investment Rating - No relevant content found Group 2: Core Viewpoints - PTA: Sino-US trade negotiations have progressed, but the market's optimistic sentiment has declined as the outcome did not exceed expectations. PTA supply has slightly shrunk, polyester production is stable with a load above 90%, and domestic polyester exports remain optimistic. However, PTA processing fees have been compressed below 200 due to lack of anti - involution information. Industry profits are affected by over - capacity from new installations. The current peak season in the downstream weaving industry may last until November, and attention should be paid to whether tariff cuts can boost domestic exports [2]. - Ethylene glycol: The inventory of ethylene glycol in East China ports remains low, with limited port arrivals and expected decline in overseas imports. New installations are pressuring prices, and the spot tightness due to low inventory is mainly reflected in the basis. Coal price increases have not provided strong cost support, and the profit of coal - based ethylene glycol has been restored. Tariff cuts from the Sino - US trade deal may increase textile and clothing export demand [2]. Group 3: Summary by Related Catalogs Market Data - **Crude Oil**: INE crude oil price decreased from 458.9 yuan/barrel on October 30, 2025, to 458.7 yuan/barrel on October 31, 2025, a decrease of 0.2 yuan/barrel [2]. - **PTA**: PTA - SC increased by 17.45 yuan/ton, PTA/SC ratio increased by 0.0054. PTA主力期价 rose by 16 yuan/ton, while the spot price dropped by 25 yuan/ton. Spot processing fees decreased by 42 yuan/ton, and the PTA仓单数量 increased by 806 [2]. - **PX**: CFR China PX price increased by 3, and the PX - naphtha spread increased by 3 [2]. - **MEG**: MEG主力期价 decreased by 14 yuan/ton, MEG - naphtha decreased by 0.2 yuan/ton, and MEG内盘 decreased by 41 yuan/ton [2]. - **Industry Chain开工情况**: PTA开工率 decreased by 0.43% to 79.66%, MEG开工率 remained unchanged at 64.41%, and polyester负荷 increased slightly by 0.06% to 89.34% [2]. - **Polyester Products**: - **Polyester Filament**: POY, FDY, and DTY prices remained stable, while their cash flows increased by 35.

Device Status - An East China PTA device with a capacity of 2.2 million tons has slightly reduced its load, and the recovery time is to be tracked [3]

1. Report Industry Investment Rating - The investment view for the polyester industry is "oscillating", with no obvious driving force, and it is expected to mainly oscillate. The trading strategy for the unilateral position is to wait and see, and attention should be paid to geopolitical risks [5]. 2. Core View of the Report - The polyester market is affected by multiple factors. The supply of PTA has slightly shrunk, the downstream load of polyester remains at about 90%, the port inventory of PTA has slightly increased, the basis of PTA has stabilized, and the profit has continued to shrink. The price of PX has rebounded, and the profit has been significantly repaired. The market is expected to mainly oscillate due to the lack of obvious driving forces [5]. 3. Summary According to Relevant Catalogs 3.1 Main Views and Strategy Overview - **Supply**: The supply of domestic PTA devices has slightly shrunk, the PTA basis has stabilized, and the operating rate of PX devices has been stable, with the PXN expanding. It is bearish [5]. - **Demand**: The downstream load of polyester remains at about 90%, the inventory of polyester factories is optimistic, and the downstream weaving has performed well recently. It is expected that the current peak season can last until November. It is bullish [5]. - **Inventory**: The port inventory of PTA has slightly increased, with a 50,000 - ton increase in inventory this week. It is neutral [5]. - **Basis**: The PTA basis has quickly stabilized, and the PTA profit has continued to shrink. It is bearish [5]. - **Profit**: The spread between PX and naphtha is $250, and the processing fee of PTA remains below 200 yuan. It is bearish [5]. - **Valuation**: The PTA price is at a neutral - low level, the profit of the reforming device has declined, and the anti - involution news has disturbed the market, causing the absolute price of PTA to rebound. It is neutral [5]. - **Macro Policy**: On October 30 local time, the Chinese and US presidents held a meeting. It is neutral [5]. - **Investment View**: There is no obvious driving force, and it is expected to mainly oscillate [5]. - **Trading Strategy**: The unilateral position should wait and see, and attention should be paid to geopolitical risks [5]. 3.2 Oil Product Fundamentals Overview - **Crude Oil**: North American crude oil inventories are at a recent low, and the US has imposed new sanctions on two Russian oil companies. The market fundamentals support oil prices, with a decrease in US crude oil inventories and a large drop in gasoline inventories, both slightly below the five - year average level. The refinery operating rate has risen from 85.7% to 88.6%. Crude oil and gasoline markets have strengthened under the tightening supply and geopolitical risks, but the reforming oil has performed relatively weakly [7][29]. - **Gasoline**: US gasoline inventories are approaching a low point. North American refinery loads have declined, and gasoline cracking profits have strengthened. The premium of reforming oil to RBOB has narrowed, the octane number profit rate of the reforming device has increased, and the refinery's oil - blending efficiency has improved. However, the reforming oil performance reflects that the oil - blending demand has not fully followed up [11][17][29]. 3.3 Aromatic Hydrocarbon Fundamentals Overview - **Aromatic Hydrocarbons**: The supply of xylene has increased, and the weakness of aromatic hydrocarbons has continued. The cross - regional arbitrage space for aromatic hydrocarbons has opened, but physical trade has not occurred. The price of pure benzene continues to suppress the disproportionation profit, and the profit of the STDP device is negative. Some producers have reduced the load of the reforming device due to the average profit of benzene [37][47][62]. - **PX**: It is the core of the price fluctuation in the polyester industry. After the listing of PX futures, its pricing is closely linked to futures. The PX spot trading is active, the price has significantly rebounded, and the profit has been significantly repaired. However, attention should be paid to the sustainability of downstream demand and geopolitical supply disturbances [58][67]. - **PTA**: Due to the large domestic PTA production capacity, the processing interval of PTA has long been maintained below 500 yuan. With the launch of new devices and new production capacities, the option - based income - enhancement scheme is increasingly widely used in the market [58][66]. - **Short Fibers and Bottle Chips**: They are in the production capacity launch cycle. Since the domestic downstream demand is relatively stable, overseas demand has become an important variable. With the implementation of the "Belt and Road" initiative, the industry has found new export opportunities and sales growth points in countries along the "Belt and Road" [58][66]. 3.4 Polyester Fundamentals Overview - **Ethylene Glycol**: The port inventory of ethylene glycol in East China is still at a low level, the port arrivals are still limited, and the import volume of ethylene glycol in the overseas market is expected to decline. New device launches have continuously pressured the ethylene glycol price. The coal price has risen, but it has not provided stronger cost support for ethylene glycol, and the profit of coal - based ethylene glycol has been repaired. The downstream weaving load may remain optimistic [87]. - **Gasoline**: The profit of Asian gasoline has significantly rebounded due to the reduction in domestic exports [89]. - **Polyester**: Polyester continues to maintain a high load, and the weaving load remains optimistic. The production of polyester has rebounded, and attention should be paid to the export performance after the tariff adjustment. The domestic polyester export is still optimistic, but the industry profit is still restricted by the over - capacity caused by new device launches [73][96][98].

1. Report Industry Investment Ratings No information provided in the reports. 2. Core Views of the Reports Polyester Industry Chain - PX: In November, with few PX unit overhauls in Asia and China, but concentrated PTA unit overhauls, PX supply - demand is expected to be weak. PX absolute prices are expected to gradually face pressure. The strategy is to follow crude oil for unilateral trading and go short on rallies, and try to shrink the PX - SC spread [1]. - PTA: In November, there are still many PTA unit overhaul plans. With better - than - expected terminal and polyester demand in October and low polyester inventory, PTA supply - demand is expected to be slightly loose with a small inventory accumulation expectation. PTA will continue to oscillate at a low level. The strategy is to follow crude oil for unilateral trading and go short on rallies, and treat TA1 - 5 as a rolling reverse spread [1]. - Ethylene Glycol (MEG): In November, domestic supply is high, overseas shipments are concentrated, and inventory accumulation is expected to be high, putting pressure on the price. The strategy is to sell out - of - the - money call options on rallies and do a reverse spread on EG1 - 5 on rallies [1]. - Short Fiber: In November, supply is expected to remain high, demand may weaken seasonally, and cost support is limited. Short - fiber prices will gradually face pressure. The strategy is similar to PTA for PF12, and try to shrink the PF processing margin when it is above 1000 [1]. - Bottle Chips: In November, supply changes little, demand is in the off - season, and the supply - demand pattern remains loose. Bottle - chip prices will follow the cost side, and the processing margin will fluctuate with raw material costs. The strategy is similar to PTA for PR, and the main - contract processing margin is expected to fluctuate between 300 - 450 yuan/ton [1]. Chlor - Alkali Industry - Caustic Soda: In November, supply is expected to increase, demand support is weak, and prices are expected to be weakly stable. The overall trend is bearish, and it is necessary to track downstream restocking rhythm [2]. - PVC: In October, PVC prices continued to decline. In November - December, supply pressure will continue due to new capacity and high - season operation, and demand is in the off - season. Prices are expected to continue to oscillate at the bottom [2]. Methanol Industry The current market is trading the "weak reality" logic centered on high port inventory. Before the Iranian gas restriction, the weak reality will continue to be priced in. The 01 - contract inventory problem cannot be solved [3][4][5]. Pure Benzene - Styrene Industry - Pure Benzene: In November, supply is expected to be loose, demand support is limited, and although the East China port inventory decreased in October, it may increase later. Pure - benzene prices are expected to have weak driving force, but attention should be paid to unit changes [8]. - Styrene: In November, supply may slightly decrease, demand is expected to change little, and the supply - demand may be in a tight - balance state. However, high port inventory will limit price increases. The strategy is to be bearish on EB12 price rebounds [8]. Polyolefin Industry PP supply recovery has slowed down due to unplanned overhauls, while PE supply is expected to increase. Demand has recovered, but the agricultural film peak is approaching. Overall, supply will increase and demand will decrease, and there is inventory pressure on the 01 - contract. The 05 - contract may have long - term low - buying opportunities, and the monthly spread is suitable for reverse spreads [10]. 3.

Report Industry Investment Ratings No relevant information provided. Core Views PVC and Caustic Soda - Caustic soda: Supply is at a high level, with weak demand support in the short - term due to shrinking industry profits in downstream alumina. However, there may be demand support in the medium - to long - term as the procurement cycle approaches and alumina has more planned production in Q1 next year [1]. - PVC: Supply returns to a high level as some maintenance enterprises resume production. Domestic downstream demand remains weak, and cost provides bottom - line support. The market is expected to be lackluster during the peak season [1]. Polyester Industry - PX: Supply is generally stable, and demand support has strengthened. It is in a situation of high short - term supply and demand but with a weak overall outlook. Cost support is limited, and the rebound space is restricted [2]. - PTA: Spot basis is weak, and the rebound is expected to face pressure due to factors such as the resumption of some device loads and the decline in oil prices [2]. - MEG: Port inventory decreases, but the upward driving force weakens. The far - month supply - demand structure is weak, and there is significant upward pressure [2]. - Short - fiber: Supply remains high, and demand has improved slightly, but the overall supply - demand drive is limited.

Report Title - The report is titled "Polyester: Favorable Tariff Policy Expected to Boost the Market" [1] Industry Investment Rating - No investment rating for the industry is provided in the report Core Viewpoint - The tariff policy is favorable, which is expected to boost the polyester market. Trade friction alleviation and potential policy support are likely to drive market improvement, though some segments face supply - related challenges [4][7][10] Summary by Catalog PX - PX processing fees are relatively strong. Due to sanctions on Russia by Europe and the US, some domestic refineries are worried, but PX supply is abundant as some plants are set to restart. PX - N is currently at $247/ton, nearly $30 higher than early October. The short - process processing range has also increased, and PX开工意愿 is strong, fluctuating with oil prices [5] PTA - There is a large potential supply pressure. New installations have increased PTA capacity by 10% compared to the end of last year. Although some plants are under maintenance in November, the supply increase pressure is just postponed. November is near the supply - demand balance, but the inventory accumulation expectation increases from December. The PTA processing fee is low, and it may continue to rebound with the support of the tariff policy, but the rebound strength is not optimistic [6] MEG - Domestic supply is at a high level in recent years. Coal - to - MEG load has reached a record high of 83%. Multiple new installations are scheduled to start production, increasing the long - term supply pressure. Import volume is expected to remain high in the fourth quarter. Current port inventory is around 500,000 tons, and the visible inventory will increase. MEG is trading sideways at a low level but may rebound under tariff policy support [8] Terminal Demand - Affected by cooling and "Double Eleven" orders, the starting rate of Jiangsu and Zhejiang looms has reached a high of 76% this year, but it is 6% lower than the same period last year. Polyester product inventories have decreased, and polyester load is expected to remain between 90% - 91% in November. The cancellation of the "fentanyl tariff" and the suspension of the 24% counter - tariff are expected to improve the terminal export market [7][10] Short - fiber - The short - fiber starting rate has slightly increased to around 95.5%. Factory inventories are at a low level, and the processing fee has slightly decreased to around 1,100 yuan/ton. Downstream pure - polyester yarn factories' starting rate is 73%, and product inventories have slightly decreased. With the support of the tariff policy, demand may improve significantly, and the processing fee is not expected to be pessimistic, with the absolute price fluctuating strongly [13] Bottle - chip - From January to September 2025, domestic demand was 7.357 million tons, a year - on - year increase of 6.8%, and exports were 4.809 million tons, a year - on - year increase of 14%. The profitability of bottle - chips has improved but has declined recently. With new installations planned to start production and the expected seasonal decline in the soft - drink market, the market pressure remains, and the processing fee increase space is limited. However, the absolute price may rebound with raw materials under the tariff policy [14]

Group 1: Report Industry Investment Rating - No relevant content provided. Group 2: Core Viewpoints of the Report - PTA prices rapidly declined due to no clear news of "anti-involution" in the PTA industry. Despite the continuous recovery of crude oil prices, PTA prices only rebounded slightly before. Although the overall load of domestic PTA plants decreased due to low processing fees, the polyester industry's profits were still constrained by overcapacity pressure caused by new production capacity and the commissioning of overseas plants. With the cost support provided by rising crude oil prices, PTA prices rebounded rapidly after a long period of low - level operation. The current downstream polyester operating rate remained above 91%, with demand slightly exceeding expectations and recent polyester sales generally high. Also, with positive news from China - US economic and trade negotiations, the market sold on positive news [2].
